Hp envy wireless keyboard and mouse without a receiver

[lulu147]

So I have a pair of hp envy wireless mouse and keyboard and they didnt come with any reciever at all. And one person I asked says it can be connected by itself through bluetooth that it doesnt need a reciever. When I turn on the keyboard and the mouse the light switches on for a second and than it switches off but the keyboard is on? When I look through bluetooth list none of the devices show on multiple devices tested. So am I rip that I dont have an receiever or can it be connected through some keyboard combination(it doesnt have any bluetooth button only on and off switch). Thank you. On the box one code is 859453-B41 if it helps to identify which hp keyboard and mouse it is
